Introduction

The Nexus® 1500+ meter is a primary and testable revenue meter that provides advanced power quality analysis functions, including support for Synchrophasor applications. It records every aspect of electrical power, including power quality and transients. The meter gives you access to this information both in real time and through reports in compliance with the IEC 61000-4-30 Class A Edition 3 and EN 50160 international standards. In this way, the Nexus® 1500+ meter provides you with a comprehensive picture of your circuits’ power usage and system reliability.

The Nexus® 1500+ meter’s capabilities ensure that essential data is captured and stored. Designed for critical and important circuit monitoring, the Nexus® 1500+ meter is a precision instrument that ensures all aspects of the electrical circuit are captured. The meter is ideal for grid monitoring, substation automation, and distribution substation reliability measurements.

Highly Accurate Energy Metrology

The Nexus® 1500+ meter incorporates advanced metrology. The unit has onboard auto-calibration capability that calibrates its internal circuitry in real time, every 10 seconds. This improves meter accuracy over time and over temperature. Auto-calibrating metrology is ideal for critical metering. Providing highly accurate measurements exceeding the ANSI C12.20 (0.1 Accuracy Class) standard and the IEC 62053-22 (0.2S Class) standard, the 1500+ provides an Energy Class accuracy of 0.06%, with typical shipping accuracies of 0.02%. Additionally, the meter has a front panel test pulse that lets you test on one pulse at low pulse weight, which you can use to quickly determine accuracy. The meter also features a new precision real time clock

that offers accuracy of 3.5 ppm, or less than 10 seconds per month drift.

New Constant CalibrationTM Architecture Increases the Stability of Measurement Accuracy

The Nexus® 1500+ meter improves on existing Nexus® architecture by providing one of the best auto-calibration methods available. Earlier Nexus® models relied on AccuMeasureTM technology that auto-calibrated the meter every 12 hours or 5 degree temperature change. Constant CalibrationTM architecture improves significantly on this, by providing considerably faster, ongoing auto-calibration.

With Constant CalibrationTM architecture, the meter utilizes a separate calibration channel to calibrate the incoming signal in real time every 10 seconds, thereby insuring that the meter experiences minimal drift in accuracy over time and temperature. With this auto-calibrating circuit, right out of the box the Nexus® 1500+ meter will stabilize its readings within 10 seconds. This means you no longer have to wait for the meter to stabilize in temperature to achieve optimal accuracy. With Constant CalibrationTM architecture, the meter will hold its accuracy throughout its operation range. Once the meter is tested, it will maintain the precise accuracy even if the operating conditions are less than ideal.

High Speed Frequency Reading for Generator Control

The Nexus® 1500+ meter offers a high-speed frequency reading of one cycle, with a frequency resolution of better than 10 mHz. This reading satisfies applications that need to respond as quickly as possible to frequency fluctuations, such as those caused by intermittent power generation in renewable power plants. A programmable rolling window average for this reading is also available.

Typical 0.02% Accuracy over Full Range

Note that typical accuracy is 0.02%; however, the meter specification should be

consulted for accuracy details.

Advanced Revenue Meter for Primary Loads

The Nexus® 1500+ unit is a primary revenue meter designed to be used for any important applications. In addition to highly accurate energy measurement, the meter features:

• Full 4 quadrant metering

• Energy load profiling: log virtually unlimited historical trending

• Time of Use perpetual calendar that supports multiple tariffs

• Transformer and Line Loss compensation: for both iron and copper and total substation losses

• CT and PT compensation: correct for errors in current and voltage transformers

• Coincidental readings: e.g., PF or VARs at time of Peak Demand, to identify number of capacitors needed, peak inefficiencies, etc.

• Load aggregation/universal metering: pulse inputs can be used to aggregate or accumulate different loads; utility products such as gas and water can also be accumulated

System Events Logging

The unit provides extensive usage information for detection of unauthorized access. The unit records:

• Resets

• Programming changes.

• Password access changes

• Time changes

• Power up/down

• Change of Firmware

Test Mode and Energy Presets

The Nexus® 1500+ meter offers a Test Mode for testing meter accuracy. Test Mode allows the meter to be tested for watt-hour and VAR-hour accuracy without affecting the stored readings. Using Test Mode, users can verify the meter’s readings over the lifespan of an installed meter without having to reset energy or disturb the load profiling and demand recording.

The Energy Preset feature allows a user to program the energy accumu-lator values upon exiting Test Mode. This lets the user compensate for accumulations missed during testing time, or easily swap a new meter for a meter being replaced.

Perpetual Time of Use for Complex Metering

The Nexus® 1500+ meter uses a perpetual Time of Use (TOU) calendar that only needs to be set up once. The TOU implementation allows the user to set up multiple tariffs to meet any contractual obligations. It also allows the user to customize any energy parameter for TOU. The 16 available TOU registers can be configured not only for TOU built-in energy readings, but also for any stored data from pulses or RTU Master readings that might need TOU functionality.
